据预测，到本世纪末，目前大气中的二氧化碳水平将增加一倍。本文研究了CO2浓度升高（550和750 μL/L）对绿色豌豆蚜生长发育和营养状况的影响。在环境CO2浓度为380 μL/L的条件下，经6代培养，7项生理指标均未受到影响。而CO2浓度升高（550和750 μL/L）则延长了若虫历期，降低了成虫寿命、雌虫产卵量和蛋白质含量，增加了总脂、可溶性糖和糖原含量。CO2浓度对若虫历期、雌虫生殖力和成虫寿命的影响与世代间的交互作用显著。CO2浓度升高对雌虫的生殖力和总蛋白、总脂和可溶性糖含量的影响是即时的，从F0代开始。从F1代开始，成虫寿命逐渐缩短，糖原含量逐渐增加。但对若虫发育的显著影响仅在三代后观察到。研究表明，CO2浓度升高首先影响蚜虫的繁殖、营养和能量供应，然后通过缩短寿命和增加葡萄糖代谢启动蚜虫的应急反应，最后导致蚜虫在CO2浓度持续升高3代后发育缓慢，可能导致种群数量下降。本研究结果将指导进一步的气候变化条件下的田间试验，以评估CO2浓度升高对豌豆蚜和其他昆虫的发展的影响，并预测绿色豌豆蚜的种群动态。
It is predicted that the current atmospheric CO2 level will be doubled by the end of this century. Here, we investigate the impacts of elevated CO2 (550 and 750 μL/L) on the development and nutrition status of the green pea aphid for six generations, which is longer than previous studies. All seven examined physiological parameters were not affected over six generations under the ambient CO2 level (380 μL/L). However, the elevated CO2 levels (550 and 750 μL/L) prolonged nymph duration, decreased adult longevity, female fecundity and protein content, and increased the contents of total lipid, soluble sugar and glycogen. There was a significant interaction between the effect of CO2 levels and the effect of generations on nymph duration, female fecundity and adult longevity. The elevated CO2 had immediate effects on the female fecundity and the contents of total protein, total lipid and soluble sugar, starting within F0 generation. The adult longevity decreased, and the glycogen content increased from the F1 generation. However, the significant effect on the nymph development was only observed after three generations. Our study indicates that the elevated CO2 levels first influence the reproduction, the nutrition and the energy supply, then initiate aphid emergency responses by shortening lifespan and increasing glucose metabolism, and finally result in the slow development under further persistent elevated CO2 conditions after three generations, possibly leading to population decline under elevated CO2 conditions. Our results will guide further field experiments under climate change conditions to evaluate the effects of elevated CO2 on the development of the pea aphids and other insects, and to predict the population dynamics of the green pea aphid.
